Cooling a power plant
The heat capacity of liquid water is 4.2 x 106 J/m3/K. This means that 1 m3 of water will be increased in temperature by 1 K when it absorbs 4.2 x 10^6 J.a. Assuming a discharge temperature allowing a 3K change, what volume of water is needed each day to cool a 500 MW powerplant operating at 40% eff...
